Results achieved

  • Class I relationship achieved

  • Midlines coincident
  • Proper axial inclination of incisors
  • Curve of Spee leveled
  • Arches aligned and coordinated
  • Alignment of both arches through derotation
  • Arch form improved
  • Aesthetic smile line was achieved 
  • Harmonic arches were achieved

Comments

  • Class I relationship was achieved by distalization of upper posterior teeth and IPR in conjunction with class II elastics.
  • Crowding was resolved with expansion and IPR in both arches. Leveling of the lower curve of Spee was performed by the intrusion of L123 and extrusion of L456.
  • Overjet was significantly reduced by retraction of upper & lower incisors in conjunction with IPR.
  • Esthetic contouring was performed in the incisal edges of upper incisors after treatment.
  • She was very pleased with final outcome and her smile.
